GAS-PRODUCER.

.Jnrrnnins and GEORGE H. ISLEY, both citizens of the United States, residing at Worcester, in the county of Worcester and Com- ,afmonwealth of Massachusetts, have invented with the contents of the chamber.

a new and useful- Improvement' in Gas-Producers, of which the following is a specification, accompanied by drawings forming a part of the same.

Uur invention relates to simplified con struction of gas producers, by means of which'the efficiency is increased and a more uniform combustion is maintained in `the gas producing'chamber; the caking of coal is prevented and the downward delivery of ashes from the prodi-loin chamber to the ash pan is controlled; an it consists in the. 'construction and arrangement of parts as hereinafter described and annexed claims.

Referring to the accompanying drawings, ltigure -1 is a side elevation of a gas pro ducer embodying 4our invention, with the lower portion shown in central section.

pointed out in the Fig. 2 1s a -plan View shown in section online 2-2 Fig. 1. Fig. 3 is a sectional view of one of the revolving arms taken on line 343, Fig. 2, looking in the direction of arrow. Figs. 4, 5 ando are detail views showing the method of union between the circular skirt and the end of the revolving arms. Similarreference characters refer to similar parts in the -di'erent views.. Y

1n the drawings,"'the casing 1, preferably cylindrical, is supported upo -columns 2. It consists of an outer metal hell 3, with the upper portion brick lined fat 4, and in# closing a gas vproducing chamber `5. At the lower portion of the chamber the brick lining 4 may be omitted, asl shown, and the metal shell 3 brought into direct conttlct 1s metal shell, in contact withthe contents of the chamber, is preferably surrounded by an annular trough or water chamber 6, inclosing a surrounding body of water 7 by means of which the temperature, of the metal shell is reduced and the formation of clinkers on the inside of thel shell is pre vented.

Below the casing 1 is a rotating ash pan .8 of greater diameterthan the lower end of Specification. of Letters Patent.

the casing and preferably 'provided with flaring sides 9. |llhe ash pan S is supported upon` conical rolls 10 journaled in bearings 11 and may be rotated by any convenient means of'rotation. Attached to and rotating with the ash pan 8 is a vertical pipe 12 for admitting a charge of air and steam to the interior of the gas producer. The pipe Patented Ill/tay "t, i212 Application filed November 23, 1910. Serial No. 533,977.

12 has a water seal connection 13 with a this instance four in number, are attached by-bolts 19 to the upper end 20 of the pipe 12. The inner end of each armis provided with a flange 21 and an opening 22 for admitting the charge of air and sgeam from the pipe 12 into the arms 18.

As shown in Fig. 3, each arm is provided at the top and on its rearward side with a slit or opening 23 beneath a removable hood or cover 24 held in position by`a hooked bolt 25 passing through the bottom of the arm' 18. The'arms 18 being attached to the rotating pipe 12 will also revolve with the rotation of the pipe 12 and the ash ,pan 8, by means of which rotation. the lower portion. ofthe contents of the chamber 5 will be carried by the'revolving arms 18 more rapidly than the upper' portionwhich is retardedby its 'friction with the walls of the chamber. This produces a plane of cleav" age in the fuel mass in' the gas producing chalmber 5 and prevents the caking of the coa As shown vin Fig. 1, a circular skirt or retaining band 26, of a diameter slightly less than the diameter of the chamber 5, is inserted in the lower part ofthe chamber approximately in the plane of the revolving arms. This skirt is preferably sup ported by attachment to the ends of the revolving arms 18 in a manner to be hereinafter described, and serves to provide revolving inclosures between the arms 18 'and' skirt 26 to secure the ashes and prevent' in anoblique position, as s own'in Fig. 1,

to adni-d'a partial Support for the mass of ashes and fuel in the gas producing cham-l ber above and bring the delivery of ashes toward.V the center of the ash pan. Between l the circular skirt 26 and the metal shell 3,

as shown in Fig; l, is an annular space 27 .gradually .increasing in width toward the this space 27 is limited by a circular shield number, to correspond with the revolving bottom of the skirt to allow clearance for ashes vorl clinkers t,which may enter between the skirt and the outer casing. Entrance to or hood 28. projecting downwardly on its inner side Aand inclosing the upper edge of thev skirt 26,v leaving only the restricted space -29 to limit the size" of parti'clesadmitte'd to the ash pan .through the annular space 27, and thereby prevent its stoppage Yor obstruction. This circular shield 28 is attached in sections to the metal shell -3 by bolts having their heads inserted in the rectangular openings, and in .F ig. 2 aportion o f these shields are removed between the lines 31, 31, in order to disclose the skirt. 26. `As shown in Fig. 2,- the skirt 26. is alsoinserted in.

sections, .in the present instance four in .the revolving arms 18 intotho chamber 5 to support combustion. As the combustion proceeds the ashes and the solid products of `combustion descend into the ash pan where theyv are crowded outwardly beneath the lower edge of the casing 1 and against the Haring sides..9 of the ash pan. The revolution of the arms `1 8 causedby their connection with the rotating pipe 12 causes the rotation of the lower portion of the con- 4 tents of the casing more rapidly than the upper portion, Athereby preventing the caking of the fuel, The contents of the chamber 5 are supported to some extent bythe shield 28 and thek skirt 26, Vboth of whichl afford. inwardly inclined surfaces Ifor the support, as well as the Adownward guidance 'of the ashes. II he centrifugal or outward 'movement of the ashes caused by the revolution of the arms 1 8 is restrained by the skirt 26 which may, as shown, be supported by attachment to the revolving arms, or if Y desired, it may\ be supported by standards resting upon the bottom of the ash pan. In either'cas'e the result is to afford revolving inclosures between the arms 18 and the skirt 26vwithin which the ashes are revolved at the bottom` ofthe fuel mass, and all outward or centrifugal movement of the ashes is restrained The skirt 26 is contiguous to the inner wall of the casing and the water chamber 7 is extended below the upper edge of the. shirt in order that it may serve to lower the. temperature and preserve the skirt from er, cessive. heat.

We claim,
